DUMPING-=CART.

SPZHCZIFTCATION forming part of Letters Patent No. 341,834, dated May11, 1886.

Application filed October ll, 1885. ScrialNo.179, l35.' (No model.)

To (7, whom it may concern:

Be it known that I, 1VIARTIN CONRAD, of Chicago, in the county of CookandState of Illinois, have invented certain new and useful Improvementsin Dump-Carts; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

The principal feature of improvement herein set forth relates to thesupport and automatic control of the tail-board. Another relates to thecatch by which the body is secured to the thills, and still another tothe provision of a permanent]y-attached seat, which may swing up into avertical position and form a dashboard.

The invention consists in the several matters hereinafter set forth, andpointed out in the appended claims.

In the drawings, Figure l is a side elevation. Fig. 2 is a fragmentarytop View. Fig. 3 1s a front elevation. Fig. t is a rear elevatron. Flg.5 is a side elevation showing the cart dumped.

The letter A is used to designate the connected parts, which constitutethe dumping portion or body of the cart as a whole. This dumping ortilting body will commonly be composed, as herein shown, of a frame, thelower side bars of which are marked A, side boards A and a frontend-board, A.

B is the wheelaxle, which is secured to the body A, and in that caseforms the axis on which the said body tilts.

O O are the thills, which are connected with each other by cross-bars cc, and extend back between the side bars, A, of the body, and arepivoted to the said side bars by a cross-rod or its equivalent at 0forward of the axle B. Vhen the body A is in a horizontal position, itsfront end rests on the thills, preferably by a bearing of thefrontcross-bar, A", of said body, directly upon the thills themselves,though the main side rails, A, may also, as shown, bear upon theprotruding end of the front cross-bar, c, which connects the thills witheach other. The said thill-bar c is shown as being arranged with itsfront face in the same plane with the front face of the crossbar A ofthe body, and as being provided with a forwardly -projecting pin, 0,intended to serve in connection with some suitable device attached tothe body, to hold the front end of said body down until the load is tobe dumped.

As one suitable form of catch on the body, D is a bent lever pivoted atits angle to the front face of the cross-bar A of the body, the shortarm of said lever depending in the form of a latch or hook, d, inposition to engage with the pin 0. The long arm of this lever D, as hereshown, extends horizontally beyond the end of the cross-bar A" to form ahandle by which said lever may be lifted and the hook disengaged fromthe pin preparatory to dumping a load.

A vertical strap don thebody forms aguide and retaining device for thelong arm of the lever D, and normally thesaid long arm of the the leverrests on a suitable support, as the side bar, A, and may rise andfallfreely. The lower end of the short arm of the lever D depends onthatside of thepin 0 toward thelong arm of said lever, and is made withan inclined surface, (1, whereby the hook engages automatically with thepin when the body of the cart drops forward upon the thills.

Proceeding to describe the principal feature of my invention,which,asstated, relates to the support and automatic management of thetail-board, E E are longitudinal bars arranged one on each side of andat or near the top of the body A, external thereto, and pivoted betweentheir ends to said body on pins or axes of movement transverse to thebody, as indicated at e. The tail-board E is fastened securely to therear ends of these pivoted bars E, and preferably by the constructionshown, in which the said bars E extend beyond the 9 depending tail-boardand thus afford room for the attachment of the outside braces, c. Thefront ends of the pivoted bars E are connected by links E with thethills, preferably through the medium of the front crossbar, c, whichprotrudes at both ends beneath the thills a sufficient distance for thepurpose. Thelinks E" are pivoted at their extremities to the ends of thecross-bar c, and also to the front ends of the bars E on transverse pinsor axes of I00 movement parallel with the pins 6. By this construction,when the body is tilted to dump I composed of two parts, A and A".

a 1oad,the tail-board E will be upheld by the bars E, while the rear endof the body descends, and on the other hand the tailboard will come backinto place against the ends of the side-boards when the body is righted.

Locating the pivotal point e somewhat below the very top edge of theside-boards A as shown, it is desirable to also place it a few inchesforward of the axle B,on which the body tilts, and to give the links E arearward inclination toward their top, so that the endboard will bethrown out clear of the upper rear corners of the side-boards A in theinitial part ofthe dumping movement. Ofc'ourse by making the rear endsof the side-boards less in height or downwardly and outwardly inclinedthese pivotal points can be otherwise located; but both for appearanceand utility I .prefer to make the side-boards of uniform height and thetail board vertical, as

. shown.

A further novel feature consists in the construction of the front endboard or gate whereby a part thereof may form a seat for the driver. Forthis purpose said end-board'is The lower part or end-board proper, A",is of the same height as the side-boards A and the upper part, A ishinged thereto or to the side-boards, and made of such length that whenthrown down into a horizontal position it will rest at its ends on theside-boards. either to the end-board or to the side-boards, or both,desirably rise in front of the end-board far enough to form a support orstop, the seat part A inits upright position, and one or the other mayserve conveniently as a projection on which to loop the lines.

By supporting the tail-board on the board E, as described, saidtail-board is relatively moved out of the way of the load to bedischarged solely by the operation of dumping the cart, and it isreturned to its place, ready for reloading the cart by the act ofrighting the body. The driver is therefore not called on to manipulateit in any way whatever, and need not release the lines or leave hisposition near the horse, wherehe will stand to disengage the lever D.When the load is discharged, the starting up of the horse will right thecart, because the thills are pivoted Cleats a,attached By making thetail-board or the tail-board and seat permanent parts of the structurein themanner set forth, much time heretofore spent in handling andhunting these parts when separate or detachable is obviously saved,andthe implement is rendered far more convenient and desirable.

It is to be understood that the term thills includes apole or any otherpart of the vehicle, which maintains its position while the dumping partis tilted, and by attachment with which the tail-board is upheld,through the medium of the bars E or their equivalent.

I claim as my invention 1. The combination, with the thills and thetilting body, of side bars pivoted between their ends to the body, andconnected at their rear ends with the'thills, and a tail-board rigidlyattached to the rear ends of said side bars, whereby the tail-board islifted as the body is dumped, substantially as described.

2. The combination, with the thills and the tiltingbody, of side barspivoted between their ends to the body, a tail-board rigidly attached tothe rear ends of said side bars, and links connecting the front ends ofsaid side bars with the thills, substantially as described.

3. The combination, with the thills and tilt ing body, of side barspivoted between their ends to the sides of the body, a tail-boardrigidly attached to the rear ends of said side bars, and linksconnecting the front ends of said side bars with the thills, said sidebars being pivoted to the sides of the wagon at or near the upper edgesof the latter, whereby the tail'board may be arranged at right angles tothe bottom of the body, substantially as described.

4. The combination,'with the side-boards and front end-board of awagon,of a seat constructed to fold upwardly, so as to form an upwardextension of the end-board, said seat being hinged on the level of theside-boards and made long enough to rest upon the latter when the seatis in a horizontal position, and a stop or stops adapted to limit theforward movement of and to support the said seat when the latter isthrown upwardly into position to form an extension of the end-board,substantially as described.

In testimony that I claim the foregoing as my invention I affix mysignature in presence of two witnesses.

MARTIN CONRAD.
